Problems solved by technology

The most important process in the production of glass bead type reflective film is the bead planting link. The traditional process mostly uses the method of directly contacting the bead planting surface with the static glass beads, which is easy to cause uneven distribution of glass beads and cannot be arranged closely. Layers of microbeads overlap, which seriously wastes raw materials and affects the reflective brightness. In addition, cold lamination is generally used, and the sinking depth of glass microbeads is not easy to grasp

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0015] Such as figure 1 As shown, the glass beads 1 preheated to 80-90°C by an oven are put into the fluidized bead tank 2, separated by a gas-permeable plate in the middle, and uniform pores are distributed on the plate, and the pore diameter is smaller than the diameter of the smallest glass beads . An electrostatic device is used to positively charge the film passing roller and negatively charge the glass beads 1 . Hot air at 80° C. is blown in from the bottom of the fluidized bead tank 2 to make the glass beads adhere to the surface of the adhesive layer 5 . After the hot-composite steel roller 3 and the rubber roller 4 are pressed together, the hot-press temperature of the hot-compound steel roller 3 is 60-70°C, and the air pressure is controlled at 0.3-0.35MPa, so that the glass beads 1 are evenly and tightly distributed on the surface of the ad...

Abstract

A process for planting glass micro ball on single layer coplane of reflection film includes preheating glass micro ball in dry oven then placing them in fluidized ball tank to have film roller attached with positive charge and glass micro ball attached with negative charge, blowing hot air into fluidized ball tank to let glass micro ball bind on surface of adhesive using hot steel roller and rubber roller to press film and glass micro ball to let glass micro ball distribute on surface of adhesive uniformly and compactly.

Description

Technical field [0001] The invention relates to a manufacturing process of a reflective film, in particular to a production process of single-layer coplanar bead planting of glass microbeads on the reflective film. Background technique [0002] Reflective film can be divided into two categories: glass bead type and micro prism according to its different retroreflection principles. The most important process in the production of glass bead type reflective film is the bead planting link. The traditional process mostly uses the method of directly contacting the bead planting surface with the static glass beads, which is easy to cause uneven distribution of glass beads and cannot be arranged closely. Layers of microbeads overlap, which seriously wastes raw materials and affects the brightness of reflection. In addition, cold lamination is generally used, and the sinking depth of glass microbeads is not easy to grasp. Contents of the invention [0003] In order to overcome the...
